To all whom it may concern:

Be it known that we, VERN SLATER and TRACY C. STUART, citizens of the United States, and residents of the city and county of Denver, in the State of Colorado, have invented certain new and useful Improvements in F ume-Dissipators, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which the invention appertains to make and use the same.

The invention relates to improvements in fume dissipators particularly intended for permeating the atmosphere of a room, or hall with pleasant odors or perfume for the purpose of counteracting disagreeable odors or fumes.

The invention has for its object the pro vision of means for thoroughly and effectively dissipating fumes with a great degree of rapidity.

7 Another object of the invention is to provide means for thoroughly mixing fumes with air for reducing the density of the fumes and for efiecting their uniform distribution.

It will be understood that while the invention is primarily intended to dissipate pleasant odors, it may be employed with equal efficiency for disinfecting purposes and for the dissipation of strong and obnoxious fumes or odors.

With these and other objects in view, the invention will now be described with reference to the accompanying drawing.

In this drawing, Figure 1 is a longitudinal sectional view of the invention; Fig. 2 is a cross sectional view, taken on the line 2-2 of Fig. 1; Fig. 3 is a cross sectional view, taken on the line 3-3 of Fig. 1; Fig. 4 is, a detail fragmental view, showingthe manner of engaging the closure with the body of the" device; Fig. 5 is a sectional view of the receptacle for retaining the fume wick; Fig. 6 is a cross sectional view of the receptacle for retaining the fume wick, taken on the line 6-6 of Fig. 5; and Fig. 7 is a view partially in section, showing the manner of connecting the fan blades.

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawing by the same reference characters.

Let the numeral 5 designate a tubular housing, one extremity of which is received over one end of a small electrical motor 6, as shown at 7 the said housing being fixedly connected with said motor by means of a band 8 passing around the housing and having its extremities connected by means of a tightening bolt 9 passed through the extremities of the said band, which extremities are bent at right angles for that purpose. By tightening the nut of this bolt 9, the housing 5 is contracted into tight engagement with the motor, thereby holding the said housing to the motor. An annular interior flange 10 disposed at right angles to the longitudinal axis of the housing 5 extends over one extremity of the motor 6 and against which the motor abuts. This flange is provided with perforations 11 therein to permit the air to circulate through the motor, the said flange 10, however, forming a stop against the passage of oil from the motor into the housing 5, as the perforations 11 are relatively small and the flan e 11 closes considerably the space between t e armature and field members of the motor.' The housing 5 is provided with an outwardly flared discharge passage 12, which communicates with the interior of the housing 5 and through which the air is driven by means of a fan 13, secured to the motor shaft 14. This fan 13 consists of a hub 15, which receives the motor shaft 14, the hub being fixedly secured to said motor shaft by means of a set screw 16 positioned in the hub and adapted to engage with the shaft 14. Arms 17 are secured to the hub 15 and extend at right angles to the axisof said hub. Fan blades 18 are adjustably threaded on the outer extremities of said arms 17, whereby the said blades may be moved either inwardly or outwardly on said arms to respectively reduce or increase the draft, or air blast. A cap 19 is removably secured to the air intake end of the housing 5, said cap 19 consisting of an annular flange, or rim 20 of less diameter than the housing 5, whereby said rim 20 may be received in said housing 5. The annular rim 2.0 is integrally formed with an end 21 of said cap, which end is provided with a plurality of perforations 22 centrally disposed in said end, and through which perforations, air is induced .into the housing 5 by the operation of the fan 13. Pins 23 are extended into the housing 5, and are received in bayonet joint slots of the rim 20, whereby said cap 19 is held in position on said housing 5 and prevented from displacement thereon. The'cap 19 is additionally held and locked to the housing 5 by means of locking strips 24:, secured to the housing 5 by means of the pins 23, while their outer extremities are turned inwardly at right angles and provided with slots'25, which. receive eye pins26. A look, .or other fastening device 27 may be passed through the eyes of these eye pins 26, wherebythe strips 24 are prevented from being disengaged'from the cap 19. These strips 2 are preferablyof spring material. A receptacle 28 is positioned in the cap 19 and receives a wick '29, which is circular to conform to the shape of the cap19, having a central openingtherethrough adapted to ,be disposedin communication with tl1e-perforations-22 to permit the air to pass through said wick into the housing 5. The receptacle 28, which contains this wick 29, is-formed by spaced apart rings 30 and 31, connected by a segmental bottom 32. The wick 29 is seated on this bottom 32 and held against lateral displacement by means of .the rings 30 and 31. When thecap 19 is in position, the receptacle 28 is engaged by the pins 23 and held by saidpins against moving into the housing 5 into contact ZWiththe fan 13. The rim 2O of the cap 19 .is provided with an opening 33 therein, and through which, 'thefume composition may be inducted. The wick 19 is composed of. a porous composition, whereby .it will absorb the fume composition, any

. residue, orsurplus being retained in the receptacle28 and absorbed-bythelwick 29 as evaporation takes place in said wick. The wick 29 is provided with an annular groove 34 therein, which is disposed adjacent the .o enin '33 said annular roove 34L receivin the fume composition and in which groove, the fume composition flows around the wick.

The cap-19 is provided with a knob 35, by which the said cap may be engaged for removal-or insertion.

In operation, the fan 13 induces the air through the perforations 22 into contact .with the wick 29, mixing the odors contained by the wick 29 with the air, the air being then expelled through the passage 12 by the fan .13, thereby circulating throughthe room a pleasant odor, or disinfectant fumes, as may bedesired.

While we have described and illustrated herein-a specific form of our invention, it is understoodthat we are not limited thereto,

and that the same may bemodified and varied without departingfrom the spirit of chamber, in directly alined open communication therewith, having air inlet means, said main casing .emboclying, a .restricted substantially closed suction chamben'having an airdischarge outlet through its peripheral wall, intermediate ,of said motor and air treating chamber ;,a filling medium; conta-ined in said air, treating chamber, freely absorptive as to a treating. agentadapted to impregnate theinCOming airin its flow-past the same intosaidsuction chamber; and a rotary. suction fan and; blower, connected to said motor, independently and snugly iii-- cased in; said suction chamber, proximately to said v{discharge outlet, the said several chambers and. elements .,be1ng ;al- 1n,ed,.,co,m-
